Omitting the f-block elements, there are 18 groups in the Periodic Table. Groups 1 and 2 contain s-block elements. Groups 3-12 contain d-block elements and groups 13-18 are made out of p-block elements. The only exception is helium is named under group 18, being a noble gas.

There are 18 groups or columns in periodic table. They are also called families. The elements with same properties are grouped together.
The horizontal rows of the periodic table are periods. The vertical columns are groups.There are 18 groups and 7 periods.

Modern periodic table has 7 periods and 18 groups.
The vertical column in a periodic table is called "The Group" and there are 8 groups in the periodic table, I through O or VIII.They are called Groups or sometimes Families. For many the periodic table has 8 groups but when you also include the transition metals, then there are 18 groups which gives you a better understanding when you are working out the electron arrangement within the atom's structure.
